Because of the 20% XP penalty you will never catch up to the other characters. Take a CR8 encounter - worth 2400 to an 8th level character and 3150 to a 7th level character, after applying 20% penalty you get 2520. As you lost at least 1/2 a level's worth of XP you need at least 10 levels to catch up to the other characters - probably more if you were already part way through 8th rather than only just 8th. (at an average of 4 weeks to level up, that's 40+ weeks i.e. a years play with missed sessions)
Worst comes to worst: Make sure you die in each of the next few combats that happen. Dieing is dead easy to engineer as a player, present yourself as a target and you will get hit, don't let the other players (including the referee) know you are on low HP in the fight. Lets face it, if you engineer the situation to die once more, you will be 2 levels lower than the rest of the party, and significanty weaker than they are, the threats that are suitable for them will be overwhelming to you.
Once you are 2-4 levels behind the rest of the party retire that character and bring in a new character - who will presumably be only 1 level behind the rest of the party, but not have the 20% penalty as you will pick a suitable race.
Tell the referee that you should be keeping your favoured class as it is a 'cultural' trait not a racial trait. Alternativly, tell the referee that the 20% XP penalty is not fun, and this is a game and supposed to be fun.
